Prices of gas aside, If you buy a 4x4 or AWD and are concerned with fuel mileage ... maybe you should have purchased a different vehicle. ( I just dumped my 10 y/o honda with awesome mpg so I could have 4x4 and I'm a cheap ass)
I received my replacement and it connected flawlessly. I did install the update, and all is fine. Caveat, if you have the Wi-Fi hotspot due to the way it works you cannot use both simultaneously.
I had the tailgate in the sun for a few hours... gently pulled them off with my fingers. Gently rolled tape residue off then a microfiber and Lucas Spray wax.
One of the things that I miss from days gone past is a light under the hood. I decided to take the issue and correct it. The following photos are my final result. Lights/switch are from Super Bright LED. Wire loom Harbor Freight. The rest I had on hand...
To further advise on this issue- The dash hyperflash issue seems to resolve itself after the vehicle warms up to higher outside temps. Last week it was 90+ and in the afternoons it stopped. It did return the next morning. It is only occurring on the left side at this time. Bulb issue I suspect.
